My Posts This: Topic  Forum		Hi

At the moment I fly on old kong power packs. yesterday I flew on Rhino 2250 30C and rly, I haven't felt very big difference.
The 450 pro of my friend with stock motor seems to have more power on old kong power than mine on rhino. And the pro is balistic on rhino...

After flight my motor is a bit warm,esc almost hot and battery too.
Pinon is not tight,just like it must be.

I use 13t , timming on 15 degres and 8khz PWM and scorpion 45A esc.

So whats wrong?

Thanks!

My Posts This: Topic  Forum		Not like it will make alot of difference, but in my experience with the Scorpion 45 ESC, I use the auto timing setting. It does a good job for me selecting the correct timing for the motor. Anything outside of that and I get "hiccup" issues at times.

I would just go through and double-check all your bearings and make sure that everything is freely spinning... check the links on all servos and in the head to make sure there's no binding anywhere. If all that is good, then I would just double-check my solder connections to make sure you don't have a cold joint anywhere causing more current draw than necessary.

Other than that, I can't really say what would be causing your ESC and packs to overheat. Somewhere you're drawing current and so being that you said it feels like it's bogging, I would look at tail belt tightness, bearings, links.. anything that moves to see if something is tight somewhere. Are your servos all in good condition and not binding internally at all??

Let me know if any of that helps and you find anything at all. Good luck man. Wish I could help more.

Mechanically my beam is in perfect condition,all bearing are OK but maybe the belt was too tight,I don't know... I've loosed it a bit and now the head turns much more freely. I havent tested it yet in flight.
I will also change the timming to auto and one again,inspect all connections.

I'll post my report after flight ,maybe this evening.

Thanks for help!

My Posts This: Topic  Forum		If you have a laser temp gun take readings at all of your connectors. I had a sudden issue with low power that I thought was a bad battery until I went to disconnect it. Almost burned my fingers on a bad Deans connector. Motor and battery were hot too. I replaced the Deans with Anderson Power Poles and all is good again. I can normally do a 6 minute hover here in the Phoenix area at 100 degrees and the motor and battery are seldom more than just warm and I'm using the 2221-8 13 tooth and a Scorpion 45 ESC. Unless you've damaged the Scorpion motor I think you're going to be spending money needlessly on a different motor. The 2221-6 and 2221-8 are the most popular motors out there for good reason.

My Posts This: Topic  Forum		Have you tried going to a 14t? I run the 2221-8 with a CC 35a on 14t and it runs a head speed of about 3k with minimal to no heat from the motor or esc.

My Posts This: Topic  Forum		I agree with Turbojoe. I personally am running the 500TH motor in mine and loving it. (That's my plug for 'em since I do fly for them) ... but I think the Scorpion motors are great as well. I think that there is an underlying issue other than the motor/ESC. Now, if you have bad motor bearings or something like that... then, of course that's going to cause an issue. However, somewhere you're drawing current and that can happen through a bad plug, as Turbojoe stated. I would highly suggest looking over everything again... maybe changing the connectors, etc. Just trying to save you some $$ and potentially the chance that you get a new motor and the same thing happens due to a plug issue or a bad solder joint, etc.

Let us know what you come up with buddy.

My Posts This: Topic  Forum		Hi

Thanks all for response!

I have never tried 14t pinon but I will.
I checked whole heli,connectors, bearings... and nothing. Maybe the ESC is the problem...
I will try to get it the pro's motor and I'll compare performances and temperature. I will also change the esc because it's too big though...

But I don't know when because I crased it day before yesterday :/

Thanks for help!

My Posts This: Topic  Forum		Try with 14T pinion, dial ur pitch up to 11,0,-11. then set ur throttle curve 0,40,60,80,100 for Normal flight, and 100,80,100 for ur Idle Up, and i think this make the heli power enough, plus switch the governer off, i ve tried with the kong power 25c and Rhino Or zippy pack 30c,the zippy make lot of diffrence

which pinion are you using? 14t or 13t. still using same scorpion motor? what is your pitch and throttle curve?

mine using scorpion 55A esc + 2221-8 motor 13t pinion, but still
not giving as much bang power as yours beam in the video.

My Posts This: Topic  Forum		Hi

My motor is still the same,Scorpion -8 and 13t. 90% flat throttle curve. 12* on pitch and 9 on cyclic. And carbon blades,with them ur heli will be much more faster. And don;t forget,timig (during tictoc) is also important.

thanks for the reply. it looks like your setup with mine almost alike.
probably mine has the same issues ( either the batt or ESC). i am using curtis YB blades , curtis paddles and tail. same th curve as yours. my pitch is -11,+11. hmm may be just try new batt first.

do your have binding issues using 12 pitch and 9 cyclic (the one
when ur give full throttle and full cyclic ) ?
mine does bind, if i use 12pitch and 9cyclic. i have to reduce the swash mix until it doesn't bind in the corner.

My Posts This: Topic  Forum		Hi,yes it binds too when I move the stick to the corner but in flight I don't move my sticks soo far so no problem.
I just returned from field ,I tried 90-83-90 curve and I can also do tictoc at the same speed... RMP are much lower but I like it.
But firstly try to chagne ur ESC if you have Scorpion bcs the SUX seriously...
